Application filed. January 9, i920. Serial No. 350,270.

To (ZZZ 'wiwmit may concern. 7

' Be it known that 1, CHARLES TV. TUMLIN, a citizen of the-United States,and a resident of the city of Chicago, county of Cooln'and State of Illinois, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification. i 1 V My invention relates to improvements 1n lubricating devices especially adapted for use in conjunction with air compressors, and

has for its object the provision of an ire-- proved construction of this character which is simple and efiicient in use, and capable of economical manufacture.

Other objects will appear hereinafter. The invention consists in the combinations and arrangements of parts hereinafter described and claimed. p

The invention will be best understood by reference to the accompanying drawings" forming a part of this specification, and in which, V I

Fig. 1, is a side view, shown partially in section, of portions of an oil compressor equipped with alubricating device embodymg the invention, and r Fig. 2, a-section taken on line 2-2 of Fig. 1'. I

i The preferred form of construction, as illustrated in the drawings, comprises an oil compressor consisting of an upper cylinder 3 and a lower cylinder 4: provided with the usual pistons operated therein and connected by the usual'piston or connecting rod 5. The

upper cylinder 3 is provided at its lower end with a suitable stufiing box 6 of any usual or desired construction. The lower cylinder t is provided at its top with a stuffing box memher 7 surrounding the plston rod 5., and an 011 well member 8 is secured thereto, as shown.

The oil well member 8' is provided at its bottom with an internally threaded socket 9 threaded exteriorly on the stuffing box member 7 and suitable'packing 10 is imprisoned by the oil well member 8 in the.

stufiing box 7, so that by securing the oil well member 8 in place,.the packing 10 iscompressed about the piston rod The oil well member 8 is filled with Waste 11, or

other absorbent material, in contact with leads into the open side of upper cylinder plying oil thereto. constantand uniform supply of oil will be 3 for constantly supe the piston rod 5, and an oil feed pipe 12 upper-end of the oil well .8 from an oil well 13 secured to the under '55 By this arrangement a applied to the piston rod 5 and the same will be adequately lubricated and wiped at each operation thereof. The oil supplied will be constantly and uniformly applied to the reciprocating piston rod'without waste.

lVhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable .of variation andmodification without departing from the spirit of the invention. 1, thereconsisting of an upper and a lower cylinder o n u I 7 pistons 111 said cylinder,

the lower end ofsaid upper cylinder and a stuffing box member on the top'of said lower cylinder surrounding said piston rod and filled with. packing box'member threaded to said first mentioned stutling box member; an oil well formed integrally with said second stufiing boX mem-,

her, said oil well surrounding said piston rod, being open at the top and filled with al sorbent material contacting with said piston rod and an oil supply well secured to said upper cylinder arranged to deliveroil desire to secure, by Let.

,' of a co-operating stufling a vertical piston-' rod connecting said pistons; a stuffing box on 8O into theopen top of said first-mentioned oil 7 well, substantially as described.

In testimony whereof I have signed name to this specification in the two SllbSCIlblUg witnesses.
